To al?, whom t may concern:

Be it known that LFREDERIOK W. SUMNER, a citizen of the United States, residing at Canton, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Stop- Motions for finding-Machines; and I do hereby declare the following to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in stop-motions and the object of my invention is to provide a simple and easily-operated device of this class, and especially adapted for usein machines in which threads are Wound upon slivers forming cotton roving.

With this object in view my invention consists in the construction and combinations of parts, as hereinafter described and claimed. In the accompanying drawings, Figure l is a top plan view of my invention, and Fi 2 is a cross-section thereof on the line 2 2 o Fig. 1 looking in the direction of the arrows.

a represents the roving, which is drawn from a suitable receptacle by means of parallel rollers, one of these rollers being lettered b, which are mounted in suitable bearings in frames c c and are driven by means of a belt passing over the pulley d, which is mounted on the shaft of the roller b. e represents a loose pulley mounted on the same shaft. As the roving is drawn between the rollers, a plurality of threads, made of linen, cotton, or other suitable material, are Wound around said roving to strengthen it and it is the object of my invention to provide means whereby if one of said threads should break the belt will be immediately and automatically shifted from the fast pulley d to the loose pulley c. The threads f are carried upon spools g, which are pivotally mounted on brackets h, secured to one face of the pulley t'. y' represents a driving-belt for said pulley. This pulley is mounted upon a hollow cylinder 7c, through which the roving passes. The cylinder is supported in suitable bearings L, mounted on the frames m.

On the exit of the cylinder c are mounted the mea-ns serving to guide the threads from spools g around the roving a and for tripping the belt-shifter. These means consist, prefwhich the threads are led and wound around the roving as the cylinder lc revolves. Adjacent the slots n and preferably mounted on lthe face of the collar or flange are movable trippers o, preferably loosely pivoted in such position that their ends project across the slots n and under the threads f, being thus held in position. The movable trippers o are preferably weighted, so that if one of them should be released by the breaking of a thread it Would quickly fly out by centrifugal force owing to the rotation of the cylinder 7c and automatically shift the belt, as hereinafter described. Pins (not shown) may be used, if desired, to prevent the guides 0 from falling in toward the center of the cylinder 7c.

p represents a standard fixed to the floor or any suitable support, and on this standard is pivotally mounted a locking-arm g, one end of which is free and the other end of which normally engages a notch in the upper part r of a slidable frame s, which slides in guides t, secured to the floor, or in any suitable way.

u represents projecting pins on the frame s forming a fork between which the belt runs, so that the movement of the frame will shift the belt.

o represents a stout spring secured to one of the frames m and to the belt -shifting frame ys, so that when the locking-arm g is disengaged from the head r of the frame s the spring will bring the frame over until one of the pins u strikes one of the guides t, thereby shifting the belt from the fast pulley d to the loose pulley c. If a thread should break, one of the movable trippers 0 would be thrown outward by centrifugal force and its end Would strike the free end of locking-arm g, forcing it up and disengaging the other end from the head r of the frame s, whereupon the belt would be immediately shifted. Instead offast and loose pulleys any other form of shifting mechanismas a friction-clutch, for example-may be used.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a winding-machine, the combination with a driving-shaft actuated from a suitable lOO source of power, of means for Winding the material under treatment with a strand of thread, fast and loose'members on said driving-shaft, means for transferring the power from one member to the other, a locking-arm for said power-transferring means, and means operated by centrifugal force adapted to directly engage with and actuate said lockingarm when the thread breaks, substantially as described.

2. In a winding-machine, the combination with a driving-shaft actuated from a suitable source of power, of means for feeding the material under treatment, revolving means for winding a thread about said material, fast and loose members on said driving-shaft, means for transferring the power from one member to the other, a locking-arm for said power-transferring means, and means connected to rotate with said thread-winding means operated by centrifugal force and adapted to directly engage with and actuate said locking-arm when the thread breaks, substantially as described.

3. In a winding-machine, the combination with a driving-shaft actuated from a suitable source of power, of means for winding the material under treatment with a strand of thread, fast and loose members on said driving-shaft, means for transferring the power from one member to the other, a locking-arm for said power-transferring means, and a tripper operated by centrifugal force adapted to directly engage with and actuate said locking-arm when the thread breaks, substantially as described.

4. In a winding-machine, the combination with a driving-shaft actuated from a suitable source of power, of friction-rolls for feeding the material under treatment, revolving means for winding a thread about said mate-- rial, fast and loose members on said drivingshaft, means for transferring the power from one member to the other, a locking-arm for said power-transferring means, and a tripper connected'to rotate with said thread-winding means operated by centrifugal force and adapted to directly engage with and actuate said locking-arm when the thread breaks, substantially as described.

5. In a winding-machine, the combination with a driving-shaft actuated from a suitable source of power, of means for feeding the material under treatment, revolving means carrying spools of thread to be wound about said material, fast and loose members on said driving shaft, means for transferring the power from one member to the other, ya locking-arm for said power-transferring means, and a tripper for each spool connected to rotate with said thread-winding means operated by centrifugal force and adapted to directly engage with and actuate said lockingarm when any thread breaks, substantially as described.
